. forretaining the retort in fixed relation to the generator under thevarying conditions of expansion by heat, and to providea gas jet whichmay soot and other obstructions.

To this end my construction and forming an oil I fully vdescribed andparticularlystated in the claim, reference being had to theaccompanylng-l drawing in which: j v Figure I, is aside elevation'v ofan oil burner according to my invention. Fig. II is a front elevation ofthe alcohol delivery device. Fig. III is a central vertical sectionpartly in side elevation of my oil burner.

Fig; IV is a longitudinal section of thejet.

Fig. V` shows a horizontal section, partly in plan view, at line X,-Fig. III.

These oil burners are usually made in .pairs mountedv on a single base7, to fit into the lire. box under two lids of a cooking stove. Theheater comprises a chamber having a circular inner wall 8, a ilo'or 9,an' outer wall 10, of sheet metal having many perforations 11,A for theblaze to issue through; a cap 12, which.rests upon the louter wall andhas a baffle ring 13 deit' withinthe chamber 8, 9.-

pending .from An intake tube 14 passes down through the ioor 9, and `hasa flange'l resting thereon.

- one end 17 to engage a pipe the oil supply pipe, thence rising to thelevel of the floor and passing in a circle'around the outer wall 10 alittle below the lower level of the perforations 1l, and supported onbrackets The retort comprises 18 that are providedwith caps 19 and screwI bolts 20; thence dropping to about the level of its starting point 17,vand provided with a jet 21, the delivery nozzle 22 of which is locatedcentrally under the intake tube 14, up intowhich the nozzle entersalittle in the county of Mason and State' be readily cleaned fromA yopened for cleaning. v[I he nozzle 22 is a invention consists 'in thecombination of parts 1 burner hereinafter more. `opensl the nozzle -to`largerinnerend opening. `The brackets 18, rigidly attached to the ,pipe29 that ymay be lof alcohol may 16 adapted atdering a stoppage. of theopening 23 liable at any moment if cleaning of the 'jet is' neglected..To facilitate this' cleaning and insure its being well done, I t aconical plug 25, having a shoulder 26, into-one end of the jet 21 andprovide a cap 27, with an "internal shoulder to engage the shoulder 26,and with a screw thread to screw upon they jet. This enables theoperator to make a tight jointeven where kerosene oil is used,

and yet permi plug like,.25'eXcepting the delivery opening 23., and hasthe same advantages. It also be cleaned from the integral with orheating chamber, hold the circular portion of the retort 16, always inits fixed relation to the perforations 11, at which the burning l takesplace, be the contraction and expansion what it may in practice. Thebase piece 7 'is formed as a pan at 30 to receive alcoho to be burneddirectly under the chamber 8,

9 to heat it .and the surrounding retort in l starting them to generategas. To pour alcohol into the pan by usual means when there is re thestove is dangerous, therefore I provide a funnel 27 that may be hung bythe loop hole28'at a safe distance from the' stove; a very smallconducting bent or swung as required to reach the pan 30, and ast'opcock31. By this means the desired quantity be easily and 'safely conductedto the pan at any time whether there is fire about the stove or not. Inoperation, oil is admitted to the retort at 17 and.

the usual stopcock in the supply pipe, not shown. Burnl the deliveryregulated by ing alcohol in the pan 30 starts the conversion of oil intogas by heating the chamber 8, 9 and retort;` this gas is delivered bythe jet nozzle 22 vinto the intake tube 14, then up into the saidchamber where it lpasses down under the baffle 13, then up over theinner `wall 8 to the burner` apertures 11 in the 'outer wall 10 where itis to be lighted by a match. The circularl por tion of the retort 16,'located near the flame,

side pulfs of air from causingv ts Athe full size of the bore to beconverts the oil into gas that would burn, but its quality as a heatproducer is greatly improved by superheating it in the chamber 8, 9Where it is retained by the battle arrangement; for that purpose andnally produces a flame of intense heat. Fairly good results are producedif the wail 8 be located farther from the wall l0, or even if it beentirely removed, but the intake tube 14, extending high up intothechamber 8, 9 and the baille 13 depending around that tube below thelevel .of its top are essential to the lbest results of this invention.

Iclaim: y In an oil burner, a heating chamber having -a floor with arising` inner wall and a central opening;

` sheet material removably attached to the Genies of this patent may beobtained for ve cents each. by addressing an outer wall of perforatedLeccese Hoor 'around and near to the inner Wall; an intake tube passlngthrough the Hoor and having a Harige resting removably thereon;

a cap resting on the outer wall and havinga bafe ring depending freelyaround the intake tube, and a delivery oil pipe located vas a retortaround the heating chamber and WILLAM' COOKE.
